Interior designer?

Ok this may sound really weird…i am 13 and i REALLY want to be an interior designer. I know what you’re thinking, “How would a 13 year old know for sure what she wants to do?” But I’ve wanted to be one since i was in like 3rd grade and i was always redecorating the living room and my bedroom, it drove my parents nuts, but at the same time they liked it. Anyway, how can I learn more about it?? Like any websites would really be helpful. And do you have to go to a special school to do interior design, or can you go to any regular collage. Thanks so much for your help!!
Also it runs in the family…my mom, grandma, and aunt did it too!

how to calculate the dimensions of an interior permanent magnet motor given it’s torque speed profile?

Hi I’m a mechanical engineering graduate student working in the area of hybrid electric vehicles. My knowledge in electric machines isn’t very good, as I’ve only recently started taking courses on them. We are trying to design a hybrid car in our university and we have been able to calculate the optimum torque-speed profile for the vehicle but would like to know how big and heavy it would be to see if it would fit properly in our car. Even if you provide correlations that give approximate answers, it would be fine, although we would like higher accuracy. The torque speed profile looks like this – the highest torque T1 is obtained from 0 rpm to N1 rpm where the torque is constant and power increases. Form N1 rpm to the max. rpm the torque decreases in inverse relation to speed providing constant power. My question – are there correlation available to calculate motor dimensions and weight from T1, N1 and max rpm?

For estimating purposes, I think that you can start with the dimensions of a standard 3-phase induction motor with a horsepower rating equal to your constant power rating and a speed equal to your N1. The increase in RPM above N1 should not affect the dimensions very much. I have looked at a technical paper that suggests that the maximum RPM for constant power operation of an IPM motor can be as much as 7.5 times N1.

You can find standard motor dimensions in the NEMA motor standard MG1. A condensed version is available as a free download:
